Abstract: 23,865. Ragona, S. Oct. 29. Cigarette - making machines.-Relates to a machine for wrapping a cork or like tip about the end of a cigarette. The cigarettes, which are generally of an oval form, are contained in a hopper 10, Fig. 1, and are caused to travel forwards in a single layer on a conveyer 12 by means of a rod 22 and tappets 23. The cigarettes on the conveyer force their way past a weighted flap 24 which causes them to assume the correct position, and under a spring-pressed bar or plate 121 which keeps the cigarettes flat and also permits any of them to be turned to position the seam correctly. The cigarettes are fed from the conveyer into a shoot 25, Fig. 8, which is provided with narrow springs 126 to compensate for any variation in the size of the cigarettes and to prevent them from turning, to which latter effect the smallness of the roller 14 of the conveyer also contributes. The cigarette is pushed from the shoot into a holder or chuck by a rod operated by a cam on the main shaft B. The holder consists of a hollow shaft 26, Fig. 2, having the forward end cylindrical and the rear end oval, and provided with a bell mouth. Mounted in the hollow shaft are a pair of spring-pressed jaws 27, which are adapted to be opened to receive or discharge a cigarette by means of a piece 32 reciprocated by means of a lever 35 and a cam 37 on the shaft F. The holder is driven from the shaft F by means of a segmental gear engaging with a gear-wheel keyed to the holder, excess movement being prevented by means of a spring-pressed bolt. The cork or like web 52 drawn from a reel 51, Fig. 1, passes through a trough 65 and between a paste-distributing roll 58 and a feeding-roll 59. The paste pot 53 has a sliding bottom-plate 54 in order to regulate the amount of paste delivered, and is also provided with an agitator 55 and a hinged cap 57. The lower roller 59 is mounted on a bell crank 61 so that the pressure on the web may be regulated by means of a spring 62 and set-pin 63. A stripper 64 is provided adjacent to the roll 58. The web, after passing through the loop 80, is fed by means of a clutch which comprises a block 69 reciprocated by a spring-controlled lever 70 operated by a pusher 71 from a cam 72 of the construction shown mounted on a shaft F. Mounted on the block 69 is a channel plate 75 having a hinged flap 76 with a spring 77, and spring-pressed clutch fingers 78 are journaled to the sides of the channel and bear upon the cork or like web on the forward or feeding stroke but are raised on the back stroke. The shears have integral actuating-arms 83, Fig. 1, pivotally connected with toggle-levers connected to a rod 86, which receives a reciprocating motion from a lever 87 operated by an adjustable cam 88 on the shaft F. Mounted in front of and below the hollow shaft 26 is a reciprocating carrier 91, Fig. 7, which serves as an endgauge for the projection of the cigarette, and as a guide to wrap the web about the cigarette. A plate 99, which is attached to the carrier 91 by springs 95, 96, has a depressed portion 100 which engages with the end of the jaws 27 and is provided with guide-pins 127 for the cork or like web. The carrier 91 receives a vertical movement by means of a lever and a cam mounted on the shaft F. This cam is so shaped as to impart a quick rise and fall to the carrier to interpose the end gauge 94 in the path of the cigarette and to leave a clear path for the web clutch, a second rise and fall to hold the web close to the cigarette while it is being attached thereto and to permit of the withdrawal of the clutch, and then a rapid rise and such further reciprocations as may be necessary owing to the irregularity of the configuration of the jaws. A pivoted arm 104, Fig. 1, carrying a flexible wiper 105 to engage the cigarette, is operated through a pusher from a cam so shaped as to give the wiper an upward movement to the jaws 27 where it remains stationary while one cigarette is being ejected and another fed thereto, a downward movement to leave a clear path above for the web, an upward movement above the jaws to enable the rotation of the jaws to complete the wrapping, and then a downward movement to press the overlapped end of the tip upon the cigarette. If the jaws are maintained stationary a tongue 109, carried by the plate 99, serves to fold one end of the severed web upward against the cigarette, and a wiper 111 operated through the bell-crank 110 from the lever 104 completes the wrapping operation. Specifications No. 6846, A.D. 1902, and No. 27,735, A.D. 1906, are referred to.
